This invention has relation to car-wheels; and it consists in certain features of construction and novel combination of parts, hereinafter referred to, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is an inner side elevation of a car wheel constructed in accordance with my invention; Fig. 2, a longitudinal vertical` section of the same detached from the journal; Fig. 3, a similar transverse view mounted on the journal; Fig. 4, a front elevation of the journal detached from the wheel. Fig. 5 is a detail in perspective of the bushing attached.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 represents the rim of the wheel, 2 the radial spokes7 and 3 the hub, which is provided with a central annular bore larger than the journal, having at its outer face a fixed cap 5, said bore being surrounded upon its inner face with an annu-lar flange or collar G.

7 represents a bushing mounted within the bore 4 of the hub and provided upon its exterior face with superficial spiral ribs S, forming intermediate oil channels or ducts 9, and intermediate the ribs with bearingblocks 9*. The bushing is provided with a central bore 10, and the wall of the bushing from nearly end to end is provided with a spiral slot or opening 11, the disposition of the slot being nearer or more at an angle to the longitudinal line or disposition of the bore of the bushing than are the spiral ribs, whereby the spiral slot opens into and communicates with each of the spiral oil duets or reservoirs. The outer cap 5 is provided with a central opening 12 for the introduction of supplies of oil, and the said supplies pass intermediate the cap and the outer end of the bushing, for which purpose there is formed a space 13, that communicates with all of the oil reservoirs or ducts and evenly distributes a supply of oil thereto.

14 represents the journal,and 15 one of the bearings, and neXt the journal and upon the bearing is loosely mounted the cap li, having an annular ange 16, adapted to it over and embrace the collar upon the rear face of the hub. Perforated lugs 17 project from the outer edge and radially from the cap, the lugs registering with three or more of the spokes of the wheel and being securely bolted thereto bymeans of bolts or screws 18. The wheel and cap are maintained in position upon the bearing of the journal by means of an annula-r collar 19, closely tting the bearing and mounted inside the bore of the cap, and secured to said bearing by means of screws 20, passing through the collar into the bearing.

Supplies of oil, as before stated, will be distributed uniformly to the several spiral grooves between the bushing and the inner wall of the hub, and as the wheel revolves said oil will be fed uniformly to the spiral slotto all points of the bearing. It will also be apparent that a sufficient quantity of oil will pass into the removable securing-cap, the bottom of which is provided with radial grooves 21,for the purpose of retaining any superfluity and gradually feeding the same between the rear face of the collar of the cap andthe rear wall thereof, and also vupon that portion of the bearing around which the cap revolves.

Having described my invention, what I claim is- 1. The combination, with the centrallybored hub, of the axle-receiving bushing iitted therein and having upon its exterior a series of spirally-tending superiicial ribs eX- tending from end to end of the bushing and forming intermediate oil.- reservoirs, spaceblocks also mounted upon the bushing and occurring intermediate the ribs, and a spiral slot formed through and through the bushing and completely encircling the same and crossing and communicating with the oil-reservoirs, substantially as speciiied.

2. The combination, with the centrallybored hub extended in rear of the face of the wheel to form a collar 6, of the bushing mounted in the bore and provided with eXterior spirally-arranged ribs forming intermediate oil-reservoirs, and with a spirally-ar- IOO ranged oil-slot Communicatingwith thereservoirs, said bushing terminating in its rear short of that of the Collar, and the axle 14,

having the bearing l5, mounted in the bush- 5 ing, the collar 19, fixed to the bearing and bearing in the collar G, and the cap 15:,secured to the Wheel and encircling the bearing and provided With the radiallyarranged grooves 2], substantially as specified.

3. In a ear-Wheel, the co1nbination,with a centrally-bored hub the diameter of which is greater than the intended bearing, a eentrally-bored bushing mounted in the hub and having radial ribs closely fitting the same and forming intermediate oil-reservoirs and intermediate bearing blocks, and a slot formed in the Wall of the bushing and communicating With the reservoirs, and an annular fixed coll-ar 16, formed upon and extend ing rearward from the hub, of a journal the bearing of which enters the bushing and is provided with a fixed collar, as 19, arranged to come against the rear end of the bushing and between the journal and the collar, a cap having an annular opening for the reception 0f the collar and for the bearing, and provided with radially extending perforated. lugs, and bolts Connecting the lugs with the spokes of the Wheel, substantially as specified. In testimony that I olairn the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.
